Sejuani vs Amumu Counter Pick
Matchup Summary
What the Data Means
Despair drains a percentage of maximum health every second from everyone standing near Amumu, and Sejuani carries the larger pool by level 18: 630 growing to 2,568 against 685 growing to 2,283. A percentage-based drain turns her durability into a liability, and the jungle record follows, with Sejuani taking only 43.7% across 229 games on patch 16.13.1.
Tantrum compounds it by permanently reducing the physical damage Amumu takes, and Sejuani’s profile is mixed with 66 base attack damage behind it, so part of her output is blunted before resistances are counted at all. Cursed Touch runs the other way: his attacks curse enemies into taking bonus true damage from incoming magic, which compounds with his own magic damage and ignores her 32 base magic resist. Her answer is a crowd control chain that needs time, since Arctic Assault stops on the first champion struck, Winter’s Wrath applies Frost stacks, and Permafrost only stuns at maximum stacks, so she must hold exactly the radius Despair is punishing. Frost Armor rebuilds out of combat and grants immunity to slows, useful between camps and gone the moment Bandage Toss connects. Her 126.7 armour applies to almost none of his damage. Amumu is rated 3 for difficulty against her 4, and Curse of the Sad Mummy entangles and stuns everyone around him, which is the moment Despair collects its full value.
